A reader wants know:

How many of you have ever received city complaints about rats in your backyard? We who live under Interlaken Park cannot NOT have rats. I use 5 electronic traps, and 2 rat motels, plus poison in many hidden places. I JUST started using a sprung rat trap. Oh, I felt SO BAD when it killed the sweet bird that has been hopping around on the ground for several years. The rats seem to learn so quickly, I never see any in the electronic nor motel traps. No animal nor human food is out.
